Chankast issues.

Ok, I only have on DC game right now, Marvel vs. Capcom 2, and when I try to run it on my DC emulator it occasionally gets super choppy and the sound skips and stops randomly. I have well over the system requirements and when I'm actually into the gameplay it runs perfectly smooth. I've read up on it and apparently some games are just like that cause the emulation isn't perfected yet, but I just wanted to make sure. Anyone else have issues with the game like that?

It's a usual problem. Did you check the Capcom Hack option on Chankast?
